  • Patent number: 11958465
    Abstract: The vehicle control system includes a braking force generating device (6, 22) configured to generate a braking force to shift a load of a vehicle to a side of front wheels thereof at an initial stage of a cornering, and a control device (31) configured to control the braking force generated by the braking force generating device. The control device calculates an additional deceleration (Gxadd) according to vehicle state information, calculates a lateral jerk equivalent value (Jy) according to the vehicle state information, and sets a lateral jerk correction coefficient (Kj) for weakening the additional deceleration. The control device corrects the additional deceleration by the lateral jerk correction coefficient (K), and calculates an additional braking force (Fbadd) to be generated by the braking force generating device according to the corrected additional deceleration.

  • Patent number: 11955917
    Abstract: A motor control system includes host control circuitry configured to generate a first control command; a plurality of motor control apparatuses configured to control a plurality of motors, respectively, based on the first control command; and reference information output circuitry configured to output reference information to one of the plurality of motor control apparatuses which is configured to control one of the plurality of motors. The reference information relates to control of the plurality of motors. Each of the plurality of motor control apparatuses corresponds to a corresponding motor among the plurality of motors and includes information sharing circuitry configured to share the reference information among the plurality of motor control apparatuses via data communication; command conversion circuitry configured to convert the reference information into a second control command; and motor control circuitry configured to control the corresponding motor based on the second control command.

  • Publication number: 20240096145
    Abstract: A noise generation cause identifying method and a noise generation cause identifying device are provided. A response correcting process corrects a sound signal obtained through a sound signal obtaining process based on obtained model information so that a frequency response of the obtained sound signal approaches a frequency response of a learning sound signal. A variable obtaining process obtains a variable output from a map by inputting the corrected sound signal to the map. A cause identifying process identifies a generation cause of a sound picked up by a microphone using the variable obtained through the variable obtaining process.

  • Publication number: 20220048400
    Abstract: An EV management system includes one or more processors, and one or more storage devices storing a program to be executed by the one or more processors. The one or more storage devices store charge/discharge request management information configured to manage charge/discharge requests from a plurality of chargers. Each of the charge/discharge requests indicates a location of a charger and a requested action specifying either charging an EV or discharging an EV. The one or more processors are configured to identify a destination of transport, select a first charge/discharge request of a first charger from the charge/discharge request management information based on the destination and the locations of the plurality of chargers, select a first EV for pursuing the transport to the destination from the plurality of EVs; and instruct the first EV to respond to the first charge/discharge request.
